Abstract: A method for fast extracting an organic pollutant in a complex system is disclosed, which includes following steps. A surface-enhanced Raman scattering (SERS) spectrum of an organic pollutant is divided to obtain P wavelength sub-intervals with overlapping regions. The P wavelength sub-intervals are screened to obtain ω wavelength sub-intervals. The ω wavelength sub-intervals are screened to obtain a required wavelength sub-interval. The required wavelength sub-interval is screened to obtain a required wavelength subset. A method and a system for fast detecting an organic pollutant in a complex system are also disclosed.
